Lewis & Clark Caverns State Park features one of the largest known limestone caverns in the Northwest. Cave access by guided tour only. Tickets will be available daily only on site from 9 am through 4:30 pm or until tickets are sold out; no reservations except for educational groups. Two tour types, the Classic Tour and the Paradise Tour will be offered. There is no access to the cave without a tour.

Extra precautions are being taken for the park’s bat populations. While White Nose Syndrome (a fungal disease that affects bats but not humans) has reached Montana, Lewis & Clark Caverns State Park staff strive to decrease additional stressors that might affect bats such as exposure to Covid-19. Any visitor choosing to take the Classic Tour of the Cave will need to bring and wear a face mask just in the areas where the bat colony resides. Those needing to go mask-free can still see the cave by taking the Paradise Tour that visits portions of the cave where bats do not live.

Lewis & Clark Caverns State Park also features camping and trails to hike or bike, a state-of-the-art visitor center, interpretive displays, a gift shop, food and beverage concessions, amphitheater, and interpretive events presented during the summer months.

The park has a large campground with 40 campsites, a tipi, and three cabins, which you can reserve online, and a group camping area, which you must contact the park to reserve.

The site encompasses 3,015 acres. The entry area is at an elevation of 4,300 feet and the caverns area is at an elevation of 5,300 feet.
